Thanks! Just amazing.
To determine the types of offenses for which criminal aliens were arrested, we obtained the Federal Bureau of Investigation (FBI) arrest histories of about 203,000 criminal aliens incarcerated in state prisons and local jails from July 1, 2004, through June 30, 2008, and 48,000 criminal aliens incarcerated in federal prisons as of December 27, 2008, for a total of 251,000 criminal aliens. Due to the large volume of arrests and offenses, we selected a random sample of 1,000 criminal aliens and analyzed their arrest records to estimate the number and types of offenses in our study population of approximately 249,000.
There were nearly 1.7 million arrest records relating to nearly 3 million offenses for these 249,000 criminal aliens. To determine the type of offenses for which criminal aliens were convicted, we analyzed data from the U.S. Sentencing Commission on federal convictions of criminal aliens from fiscal years 2003 through 2009 and conviction data from five states—Arizona, California, Florida, New York, and Texas—from fiscal years 2005 through 2008. We selected these five states based on the number of SCAAP criminal aliens. Collectively, these states accounted for about 70 percent of the SCAAP criminal alien population in fiscal year 2008.
